“I have the former lined pant, the Flanstone & was unsure if I'd be happy with the replacement pant - the Mariner because it's a little less slim fit. Turns out it's slim enough and is the same great quality as the other. My flannel lined pants from Prana & Patagonia are too bulky. Jetty has is right. From the outside, you can't tell they're lined. the pants are super comfortable and warm. Pockets deep enough for large phones.”
